As many embodiments may be made of this inventive
concept, and as many modi?cations may be made of the
embodiment hereinbefore shown and described, it is to
be understood that all matter herein is to be interpreted
I claim:
In a dispensing mechanism, in combination, a vertical

a plurality of shelves each pivoted at one edge on said
an adjacent notch.
Obviously, when it is desired to move all of the shelves
back to horizontal position, for reloading or the like, it is
only necessary for an operator who has access to the
mechanism to grasp the operating handle 44 and press it
towards the perpendicular ?ange 33, which action releases
the pawl point 41 from engagement with any adjacent
notch, and moves the same out of the range of the ratchet
bar, whereupon the assembly including the resetting plate
and its associated tape may be moved downwardly to the
bottom of the slot 21. As the tape passes each actuating
lever 20 the associated shelf is obviously forced out
wardly to horizontal position.
Any desired conventional means may be employed for
actuating the ratchet bar 53 and, in the illustrative em
bodiment shown, take the form of a link 60 which is pivot
ally connected as by means of a pivot 61 to the lower
extremity of ratchet bar 53. A second link 64 is pivotally
connected as by means of a pivot 65 to the other end of
link 60, ‘and the other end of link 64 is in turn pivotally
connected as by means of a pivot 66 to a reciprocatory
operating bar 67. A mount of any conventional form
may be provided and is generally indicated as of channel
’form at 68. The lower side walls 13 of channel member
11 are secured to the side walls of member 68 in any
desired manner as by rivets or bolts. An outer housing
plate, an actuating lever on each shelf adjacent said slot,
a coiled ?exible tape mounted at the top of said plate and
extensible to close said slot, a reset plate secured to the
free end of said tape, a pawl pivotally mounted on said
reset plate, a ratchet bar having a plurality of notches
therein vertically mounted adjacent said slot, said notches
being positioned apart a distance equal to the space be
tween adjacent shelves, operating means to lift said ratchet
bar a distance of one shelf space comprising a handle
and angularly disposed links pivotally secured to said
handle, to each other and to said bar, said notches engag
ing said pawl upon upward movement of the said bar
thereby lifting the said reset plate and moving said tape
upwardly into said housing to expose said slot adjacent the
actuating lever of a single adjacent shelf, whereby‘said
actuating lever is permitted to move into said slot and
said shelf falls by gravity to drop its contents, said reset
plate having a perpendicular ?ange thereon engaging with
said pawl to limit pivotal movement thereof when engaged
by said notches, and upon downward movement of the
said bar to bias the said pawl from the path of the said
notches, and an operating lever extending from said pawl
for moving said pawl out of engagement with said notches
for downward movement of said slide block to reset said
shelves, said pawl being triangular in shape and pivoted
at its apex and having an operating point engageable with
69 may be provided, and is preferably enclosed, as is the
said notches and a locking point on the opposite side of
entire assembly which is mounted in a conventional vend
its pivot for engagement with said perpendicular ?ange,
ing casing 70 of any desired form. Suitable coin actuated
mechanism 71 of conventional design may be employed 40 said ratchet bar having elongated vertical slots therein
‘and lugs ?xed to said vertical plate engaging in said slots
to control the operation of the actuating lever 67. The
for limiting the vertical movement of said ratchet bar and
mounting and arrangement of the device comprise no part
to prevent displacement of the said pawl from engagement
of the instant invention, and are shown here schematically
and for illustrative purposes only, the invention residing 45 with said notches.
